(57) Apparatus for reading optical information such as a bar code and including a handheld
reader containing a reading sensor (8). An image of the optical information is imaged
by light reflected from the optical information, via a reflecting mirror (5), a lens
(6) and a diaphram member (7), onto the reading sensor (8) so that the image is converted
into an electric signal. A pair of LEDs (10, 11) are disposed on both sides of the
image sensor (8) so that the images thereof are imaged near the optical information
by light from the LEDs (10, 11) through the diaphram member (7), the lens (6) and
the reflecting mirror (5). The LEDs (10, 11) and reading sensor (8) are controlled
so that the LEDs (10, 11) are disabled from emitting light while the reading sensor
(8) performs the reading operation of the optical information. Instead of LEDs (10,
11), optical fibers can be used.
